“…Williams et al (1990) concluded that most pastures in summer-dry hill pastures contained low proportions of white (Trifolium repens l.) and subterraneum (T. subterraneum l.) clovers. This was associated with considerable variability in distribution related to such factors as drought, soil fertility, grazing intensity and frequency and temperature at contrasting sites (Suckling et al 1983;macFarlane & Sheath 1984). Gillingham et al (2003a) suggested that as a result of this variability in clover content, which was also related to slope and aspect, a differential N and P fertiliser application strategy on a range of hill pastures could result in higher overall pasture productivity, than from the use of P fertiliser alone.…”

From 2000 to 2002 a trial series was established on seven farms from Wairoa (northern Hawke's Bay) to Moeraki (North Otago), with contrasting amounts of spring-summer rainfall, to evaluate the pattern of pasture responses to a range of rates of nitrogen (N) fertiliser and a range of soil phosphorus (P) levels. Small plots excluded from grazing were established on flat to gently sloping land containing pastures that had been established for many years. This paper describes the clover and grass component production responses to N fertiliser and to a range in soil P status at each site. In early spring, in all years, the grass components of pasture at all sites except Marlborough, showed a significant response in dry matter (DM) production to N fertiliser applied in mid winter. These responses A07058; Online publication date 6 June 2008 Received 27 July 2007 accepted 13 March 2008 continued into late spring-autumn at most sites/ years. The consistency from year to year of the relative grass response in spring to N fertiliser allowed significant regression relationships to be developed for the 3-year dataset for the North Island sites. The same result did not occur in Marlborough, presumably because low rainfall limited pasture growth, or at Moeraki (not measured). The effects ofN fertiliser on clover production throughout the total season tended to be the opposite of those for grass production. There was generally no response to N fertiliser in early spring but a marked and consistent decline in clover production in late spring-autumn with increasing rate of N fertiliser application. Compared with clover production from plots that received 90 kg N ha -1 , the average clover production in late spring-autumn from plots that received zero N application, was up to the order of three times greater at the Wairoa, Puketapu and Wallingford sites, and about 50% greater at the Waipawa and Wairarapa sites. There was a consistent response by clover in both early spring and in the late spring-autumn seasons, to an increase in soil Olsen P test. On the four northern-most sites an increase in Olsen P test from less than 10 to about 20 raised clover production by about 100% in early spring and by a greater proportion in late spring-autumn. This was in direct contrast to the absence of a response by the grass component during the same period. The management implications of the contrasting effects of N and P fertilisers on pasture clover and grass composition are discussed.

“…Relative peak flowering times and maturity rankings were as expected (Scott 1972;Cocks & Phillips 1979;Suckling et al 1983). Whereas the long-term compatability of floweringheseeding time and moisture availability can only be tested over several years, the flexibility and desirability of extended flowering times and intensities as exhibited by Bacchus Marsh and Mt Barker should be recognised.…”

“…At Ballantrae, 'Mt Barker' flowered only 6-9 days before 'Tallarook' , instead of an expected interval of 20--26 days (Suckling et al 1983;Collins et al 1984). Later than expected flowering of 'Mt Barker' was also recorded at Whatawhata in 1982 (Sheath & Macfarlane 1990b) whereas at other sites, such as Kaikohe (Rumball & Cooper 1990) the flowering date of 'Mt Barker' was more in line with expectations.…”

Herbage production and population regeneration characteristics of nine subterranean clover (Trifolium subterraneum L.) cultivars were measured on a steep, dry, north-facing hillside at Ballantrae Hill Country Research Station, New Zealand. A close, linear relationship (r = 0.914) between subterranean clover herbage production and flowering date was observed. The latest flowering cultivar, "Tallarook', gave the highest herbage yields (average =770 kg dry matter (OM)/ ha per year) and, in the latter stages of the evaluation, was superior in seedling regeneration. Exceptions to the general relationship between time of flowering and herbage accumulation were: 'Howard' in 1983/ 84-higher production than predicted because of exceptionally good seedling regeneration; 'Clare' in both years-lower production because of poor persistence «3 years); and 'Mt Barker' in both years-lower production because of poor initial establishment. The mid-late or late-flowering cultivars 'Larisa', 'Mt Barker', and 'Tallarook' all appeared tolerant of intensive sheep grazing and persistent in this environment as a result of their predominantly small-leaved, dense growth habit. A late-flowering cultivar of similar morphology to "Tallarook', but containing little or no oestrogen, would be best suited to environments similar to Ballantrae.
